OBJECTIVE: To explore the role of antibiotic-eluting absorbable calcium sulfate in treating periprosthetic infection after one-stage revision of knee arthroplasty. METHODS: A retrospective analysis was performed on 36 patients(36 knees)who underwent phaseⅠrevision for periprosthesis infection after total knee arthroplasty from January 2018 to March 2022. All patients were underwent knee cavity puncture before operation and had positive results of aseptic body fluid culture, 21 patients received revision combined with antibiotic loaded calcium sulfate at stageⅠ(calcium sulfate group) during operation, and 15 patients underwent renovation at stageⅠ(revision group). There were 9 males and 12 females in calcium sulfate group, aged from 54 to 76 years old with an average of(67.6±6.2) years old. There were 15 patients in revision group, including 4 males and 11 females, aged from 60 to 75 years old with average of (69.6±4.1) years old. The levels of serum C-reactive protein (CRP), interleukin-6 (IL-6) at 7, 14, 30 and 90 days after operation were compared between two groups, and the rate of end-infection control at follow-up were compared. The systemic antibiotic application time, hospital stay and postoperative complications were observed between two groups. RESULTS: Calcium sulfate group were followed up for 12 to 29 months with an average of(18.9±4.2) months, and the infection control rate was 90.5%;while revision group were followed up 18 to 29 months with average of (21.6±3.7) months, and the infection control rate was 86.7% (13/15). There were no significant differences in follow-up time and infection control rate between two groups(P>0.05). Postoperative levels of CRP and IL-6 at 7, 14 and 30 days in calcium sulfate group were (32.79±11.48), (15.50±6.52), (9.36±3.32) mg·L^-1 and (17.31±6.15) pg·ml^-1, respectively;which were lower than those in revision group (40.65±11.32), (30.15±10.57), (18.97±5.86) mg·L^-1 and (25.54±6.73) pg·ml^-1, had statistical differences(P<0.05). There were no significant differences in IL-6 levels at 7 and 14 days after operation and CRP levels at 90 days after operation between two groups (P>0.05). The hospitalization time and systemic antibiotic application time in calcium sulfate group were (18.4±2.2) and (63.5±21.4) d, respectively;which were better than those in revision group (20.5±2.4) and (82.7±16.9) d, and had statistical differences(P<0.05). No significant wound complications and hypercalcemia were observed in calcium sulfate group. CONCLUSION Antibiotic eluted absorbable calcium sulfate could be used to treat periprosthetic knee infection, significantly reducing CRP levels in the early postoperative period, shortening hospital stay and systemic antibiotic application time, but it does not significantly improve the control rate of revision infection at stageⅠ.

Drugs and pesticide residues in broiler feed can compromise the therapeutic and production benefits of antibiotic (ANT) application and affect gene expression. In this study, we analyzed the expression of 13 key pancreatic genes and blood physiology parameters after administering one maximum residue limit of herbicide glyphosate (GLY), two ANTs, and one anticoccidial drug (AD). A total of 260 Ross 308 broilers aged 1‍-‍40 d were divided into the following four groups of 65 birds each: control group, which was fed the main diet (MD), and three experimental groups, which were fed MD supplemented with GLY, GLY+ANTs (enrofloxacin and colistin methanesulfonate), and GLY+AD (ammonium maduramicin), respectively. The results showed that the addition of GLY, GLY+ANTs, and GLY+AD caused significant changes in the expression of several genes of physiological and economic importance. In particular, genes related to inflammation and apoptosis (interleukin 6 (IL6), prostaglandin-endoperoxide synthase 2 (PTGS2), and caspase 6 (CASP6)) were downregulated by up to 99.1%, and those related to antioxidant protection (catalase (CAT), superoxide dismutase 1 (SOD1) and peroxiredoxin 6 (PRDX6)) by up to 98.6%, compared to controls. There was also a significant decline in the values of immunological characteristics in the blood serum observed in the experimental groups, and certain changes in gene expression were concordant with changes in the functioning of the pancreas and blood. The changes revealed in gene expression and blood indices in response to GLY, ANTs, and AD provide insights into the possible mechanisms of action of these agents at the molecular level. Specifically, these changes may be indicative of physiological mechanisms to overcome the negative effects of GLY, GLY+ANTs, and GLY+AD in broilers.

OBJECTIVES: Bloodstream infections in emergency patients have a high incidence, severe disease progression, and rapid deterioration. Early administration of appropriate antimicrobial agents is crucial for improving patient outcomes. This study aims to investigate the incidence, pathogen distribution, and antimicrobial resistance patterns of bloodstream infections in emergency patients, providing a reference for rational antibiotic use in clinical practice. METHODS: Medical records of patients diagnosed with bloodstream infections in the emergency department of a hospital in Hunan Province between January 2018 and October 2022 were retrospectively collected. Clinical characteristics of bloodstream infection patients were analyzed, and the distribution trends and antimicrobial susceptibility of clinical isolates were examined. RESULTS: During the study period, 2 215 blood culture samples were submitted from the emergency department, with a positivity rate of 13.27%. After excluding eight cases with missing data or suspected contamination, 286 patients with bloodstream infections were included, with community-acquired infections accounting for the majority (85.66%). The most common primary infection site was the urinary tract (24.48%), followed by respiratory tract infections (20.28%) and biliary and intra-abdominal infections (17.13%). The 30-day mortality rate of bloodstream infections was 16.08%. A total of 286 pathogens were isolated, including 181 (63.29%) Gram-negative bacteria, primarily Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa; 101 (35.31%) Gram-positive bacteria, mainly Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus pneumoniae; and only 4 (1.40%) fungal isolates. Antimicrobial susceptibility testing showed that the key Enterobacteriaceae strains exhibited resistance rates of 2.4% to carbapenems, 16.3% to piperacillin sodium and tazobactam sodium, and 15.3% to ceftazidime, with no detected resistance to tigecycline or polymyxins. The main non-fermentative bacteria showed resistance rates of 29.6% to piperacillin sodium and tazobactam sodium, 13.3% to cefoperazone sodium and sulbactam sodium, and 27.1% to quinolones. Among Gram-negative bacteria, multidrug-resistant strains accounted for 40.9% (74/181), with carbapenem-resistant Escherichia coli and Klebsiella pneumoniae detected in 5.4% (5/92) and 13.6% (6/44) of cases, respectively. No carbapenem-resistant Pseudomonas aeruginosa was identified. Among Gram-positive bacteria, resistance rates to penicillin G, rifampicin, and cefoxitin were 74.7%, 4.2%, and 50%, respectively, with only 3 cases of resistant to glycopeptide antibiotics. CONCLUSIONS Bloodstream infections in emergency patients are predominantly community-acquired, with Gram-negative bacteria being the most common pathogens. The isolated pathogens exhibited relatively low resistance rates to commonly used clinical antibiotics.

OBJECTIVE: The objective of this study was to investigate the clinical efficacy and safety of treating sepsis patients with Xuebijing injection (XBJI). METHODS: We conducted a retrospective analysis of 418 patients who experienced severe infections and were treated with XBJI from June 2018 to June 2021. Propensity score matching was used to match the patient cases. The study population included 209 pairs of cases (418 individuals), and the analysis included data from before and after a 14-day course of treatment with carbapenem alone, or carbapenem with XBJI. RESULTS: There were no significant differences in the 14-day mortality or length of hospital stay (P > 0.05) between the two groups. The combined treatment group had more patients with C-reactive protein that returned to normal levels (compared to baseline) than the non-combined treatment group (14.4% vs 8.1%; odds ratio [OR]: 0.528; 95% confidence interval [CI]: 0.282-0.991; P = 0.026). Similarly, the combined treatment group had higher procalcitonin attainment rate (55.0% vs 39.7%; OR: 0.513; 95% CI: 0.346-0.759; P = 0.001) than the non-combined treatment group. Further, more patients in the combined treatment group achieved normal creatinine levels than in the non-combined treatment group (64.1% vs 54.1%; OR: 0.659; 95% CI: 0.445-0.975; P = 0.037). CONCLUSION The combination of XBJI with carbapenem did not reduce the 14-day mortality rate of patients with severe infection, but it was able to reduce the level of inflammatory factors in patients with sepsis, and had a protective effect on liver and kidney function.

Platelets not only have hemostatic function, but can also directly or indirectly recognize pathogenic microorganisms and the signals they produce to capture and destroy them through membrane receptors. They can collaborate with various components of the body's immune system by releasing of intraplatelet particulate matter, cytokines and chemokines to perform bactericidal functions. And it can also play a bactericidal role by swallowing pathogens, releasing antimicrobial proteins and chemokines and activating and enhancing other specialized anti-inflammatory cells bactericidal effect, such as leukocytes and so on. However, the bacteriostatic composition and bacteriostatic mechanism of platelets remain unclear, so attention should be paid to the immune mechanism and bacteriostatic effect of platelets.

At present, effective antibiotics and comprehensive symptomatic/supportive treatment as early as possible are mainly used for the treatment of severe pertussis in clinical practice. However, some children with severe pertussis have unsatisfactory response to commonly used drugs and treatment measures in the intensive care unit and thus have a high risk of death. Studies have shown that certain treatment measures given in the early stage, such as exchange transfusion, may help reduce deaths, but there is still a lack of uniform implementation norms. How to determine the treatment regimen for severe pertussis and improve treatment ability remains a difficult issue in clinical practice. This article reviews the advances in the treatment of severe pertussis, in order to provide a reference for clinical treatment and research.

OBJECTIVE: The quick sequential organ failure assessment (qSOFA) score, which includes mentation, systolic blood pressure, and respiratory rate, was developed to identify serious sepsis in out-of-hospital or emergency department (ED) settings. We evaluated the ability of the qSOFA score to predict poor outcome in South Korean ED patients with suspected infection.METHODS: The qSOFA score was calculated for adult ED patients with suspected infection. Patients who received intravenous or oral antibiotics in the ED were considered to have infection. In-hospital mortality rate, admission rate, intensive care unit (ICU) admission rate, length of hospital stay (LOS), and lactate levels were compared between the qSOFA score groups. Receiver operating characteristic curves and area under the receiver operating characteristic curve values for in-hospital mortality were calculated according to qSOFA cut-off points and lactate levels.RESULTS: Of 2,698 patients, in-hospital mortality occurred in 134 (5.0%). The mortality rate increased with increasing qSOFA score (2.2%, 6.4%, 17.5%, and 42.4% for qSOFA scores 0, 1, 2, and 3, respectively, P<0.001). The admission rate, ICU admission rate, LOS, and lactate level also increased with increasing qSOFA score (all P<0.001). The area under the receiver operating characteristic curve values for predicting in-hospital mortality associated with qSOFA score, lactate ≥2 mmol/L, and lactate ≥4 mmol/L were 0.719 (95% confidence interval [CI], 0.670 to 0.768), 0.657 (95% CI, 0.603 to 0.710), and 0.632 (95% CI, 0.571 to 0.693), respectively.CONCLUSION: Patients with a higher qSOFA score had higher admission, ICU admission, and in-hospital mortality rates, longer LOS, and higher lactate level. The qSOFA score showed better performance for predicting poor outcome than lactate level.

PURPOSE: Periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome is a leading cause of periodic fever in children. This study describes the clinical characteristics of PFAPA syndrome in patients from a single center.METHODS: Thirteen children diagnosed with PFAPA syndrome at Seoul National University Children's Hospital were included in this study. Retrospective medical chart reviews were performed.RESULTS: Among the 13 patients, 8 (61.5%) were male. The median follow-up duration was 3.3 years (range, 10 months–8.3 years). The median age of periodic fever onset was 3 years (range, 1–6 years). All patients had at least 5 episodes of periodic fever and pharyngitis, managed with oral antibiotics, before diagnosis. The median occurrence of fever was every 3.9 weeks and lasted for 4.2 days. All patients had pharyngitis and 12 (92.3%) had cervical lymphadenitis. Blood tests were performed for 12 patients, and no patients had neutropenia. Both the C-reactive protein and erythrocyte sedimentation rate were elevated at medians of 4.5 mg/dL (range, 0.4–13.2 mg/dL) and 29 mm/hr (range, 16–49 mm/hr), respectively. Throat swab cultures and rapid streptococcal antigen tests were negative. Nine (69.2%) patients received oral prednisolone at a median dose of 0.8 mg/kg, and in 6 (66.7%) patients, fever resolved within a few hours. Three (23.1%) patients received tonsillectomy and adenoidectomy.CONCLUSIONS: PFAPA syndrome should be considered when a child presents with periodic fever along with aphthous stomatitis, pharyngitis, or cervical lymphadenitis. Glucocorticoid administration is effective for fever resolution and can reduce unnecessary use of antibiotics.

BACKGROUND AND OBJECTIVES: Acute epiglottitis is a life-threatening condition that can result in airway obstruction. The present study reports clinical features, management and patient outcomes in an acute epiglottitis. SUBJECTS AND METHOD: Included in our retrospective study were 315 patients who were admitted with the diagnosis of acute epiglottitis between January 2006 and July to the department Otolaryngology-Head and Neck surgery, Hallym University Sacred Heart Hospital 2018. The diagnosis of acute epiglottitis was established by confirmation of inflamed epiglottis using laryngoscope or computed tomography. RESULTS: Among 315 patients, 89 cases (28%) and 83 cases (26%) were found in the fifth and fourth decades, respectively. The mean age of patients was 45.0±13.94 years. The male to female ratio was 1.33:1. A total of 75 patients (23.8%) had co-morbidities, with hypertension (13.6%) being the most common. Fever was relatively uncommon, whereas most patients complained of sore throat. Ceftriaxone was the most common empirical antibiotic regimen prescribed and the use of steroids did not affect the length of hospital stay. Nine patients required airway intervention, including eight who underwent endotracheal intubation and one emergency tracheostomy. In patients who need airway intervention, systolic blood pressure, body temperature, respiratory rate, heart rate, white blood cells and the proportion of dyspnea were significantly higher in comparison to the patients without airway intervention. CONCLUSION: Although acute epiglottitis often has nonspecific symptoms, it may lead to sudden dyspnea and unstable vital signs, so an in-depth understanding of this disease is needed.

Postinfectious glomerulonephritis (PIGN) is most commonly caused by Streptococcus pyogenes in children, but PIGN associated with other pathogens has been described in the literature. A previously healthy 6-year-old boy was admitted with complaints of cough, fever, and right chest pain. The patient was diagnosed with pneumococcal bacteremia and influenza A virus infection and treated with antibiotics and antiviral agent. During hospitalization, generalized edema, hematuria, proteinuria, and increased blood pressure were observed; therefore, we started administering diuretics. The boy was discharged with gross hematuria, and even microscopic hematuria disappeared 14 weeks after discharge. We report a case of PIGN associated with bacteremic pneumococcal pneumonia and influenza A virus infection in children. A urine test and blood pressure measurement should be considered for the early detection of PIGN in children with pneumococcal or influenza A virus infection when they present with nephritic symptoms.
